Question Dear expert
As you know, you can disassemble a .NET-based executable file using 'ildasm.exe' application provided by the .NET Framework and then examine the intermediate language codes. Two questions arise here:
1.Is it possible to change the intermediate code and the
recompile it? In fact I worry about the security
issues!
2.Could one de-compile the intermediate code into the
original source code or into other .NET languages? Is
there any encryption or obfuscation measures taken to
provide .NET code security?
Thank you very much
Answer It is very easy to de-compile obfuscated code and make changes to it, to secure your assemblies you should try obfuscation. Visual Studio comes with a free DotNet Obfuscator community edition. You can very easily find many other advanced obfuscators on internet, which can make dotnet de-compiling difficult. But as a security expert, nothing is ever secured.
